Fixturing

Anyone have any good resources for fixturing? Besides going all out for a design engineering degree.

  • If you do want to set 30 parts and measure them all at once, then yes. The chuck and vice isnt gonna fly. I stayd away from measuring many parts at once kind thing. I ran one part at a time. This way you can monitor each part and make modifications if needed.

    So its a trade off I guess.

    Having 30pc measured at once can be a winner, but also can be a looser.

    For example, and there many examples. Say, one of the part is not seated property, you will not know that untill you ran all 30. So you will have a large report with one part being bad. The boss want to have a complete good report, you have to re run 30pc again. You wont be able to just run that part, because you have a loop.

    I am sure there are ways, just saying it may not always beneficial to run many parts at once, thats all.. Ofcourse its much faster to have a fixture that is designed to measure 30pcs, than gluing and such. But, it also is expensive and it takes time to make one.

    Most places i worked at, we did not have the time to make one. So, i work with what i had, chuck and vices and magic markers. Which also work great if you have small parts. You can easily set up 30pc using the marker and it will hold!


    That's all we do here, run tons of parts. Take one down, put a new one on and hit go, take it down, put a new one on and hit go. So on till all crap ton are done.

    Then on the the next million piece run of another part. Same thing, set it up, put it on, take that one down, put on another and hit go. Fixtures come in handy. Just wish I could convince my boss that we need to calibrate the tip more than once a week.
